Answer:
y = - 3x + 17
Step-by-step explanation:
Note that slope is a measure of the rate of change of a linear function.
Express the function in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
here m = - 3, thus
y = - 3x + c ← is the partial equation
To find c substitute (5, 2) into the partial function
2 = - 15 + c ⇒ c = 2 + 15 = 17
y = - 3x + 17 ← is the linear function
